Probably the ideal solution, I'd have thought. It's with you when you're climbing, so no worries about theft, but in a place it can't easily be lost from. One of my pals carries his wedding ring this way.
I'd second those who advise against cord round the neck. There's a reason company ID badge lanyards have those easy-fail clips in them. However, carry your ring on something like that and if it does get snagged and break, nine times out of ten that's your ring gone. Keeping it instead in a secure pocket in your chalk bag reduces the chances of that happening considerably. Also, you tend to be aware of whether you still have your chalk bag with you (it's almost a talisman for some climbers!) And if the chalk bag does contrive to detach itself and make a bid for freedom, it should be a whole lot easier to find than a ring.
If the gold necklace idea is because you want something sparkly, you could always bling up your chalk bag!
(And to timjones: you missed the bit about assessing the impact of the risk if it were to occur. A low low likelihood/low impact risk can probably be accepted; low likelihood/high impact really ought to have some mitigation. Strangulation would be rated a fairly high impact if I were doing the assessment...)
P.S. Congratulations!
